To @ZZ whom t may concern:

, ,Beit known that I, CHARLES W. DAKE, a citizen `of the United States', residing at Grand Rapids, in the county of Kent, btate 'of Michigan, haveinvented certain new and although the governor lmeans can be appliedto control. engines of any type.

liiy invention is especially designed, however, tor useu in governing elastic-iluid tur-- bine-engines in which the turbines are run at high rate oispeed.

lbiects relating to details of construction will deiinitely appear from the detailed description to follow. n

accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined, and point-- ed out in the-claims.

Astructure embodying the features of my invention is clearly illustrated in the accom panying drawings, forming a part of this speciiication, in which- Figure 1 is a detail sectional view, in broken section, through a complete governor em bodying the features of my invention; and Fig. 2 is a plan view of the funnel-shaped receptacle 2 withinmy improved governor.

Similar numerals of reference refer to similar parts throughout both the views.

Referring to the numerals of reference, the main casing 1 of my improved governor is supported on a suitable base-piece 11, which is secured to a bracket 18, which is secured, preferably, to the side plate 27 of a turbine engine by screws 24, which serves asa support for the same.

A funnel-shaped chamber is formed in the upper part of this casing, within which is al funnel-shaped receptacle2, supported o n a vertical shaft 3, which extends down into suitable bearings and is ,adjustable up and` down'y by the screw 16, retained in place by the lock-nut 17. This vertical shaft 3 is revolved by a worm-gear 12, engaging a worm 13 (indicated by dotted lines in Fig. 1) on the main shaft 190i the turbine.4 The shaft 19 of the'engine is provided with a bushing 20, and lubricant is supplied thereto by a .L i Y h Suitable bushings 14 are mounted on theshaft 3, which provides a suitable bearing for the same.

A stuiiingbox 10 is around the shaft 3 and is accessible through openings 1 y A steam-jacket 7 connectsby pipes 25 25 to the casing 27 oi the turbine, and a pipe 26 leads there-from to insure circulation-oi' steam or other elastic iiuid in the jacket 7. V

Extending down into the revoluble receptacle 2 is the funnel-shaped bottom of a receptacle 9, having an opening 9 at the center.I This vbottom forms an annular space around the revoluble funnel-shaped receptacle 2. This receptacle is accessible by removing the plug 8. A pipe or tube 8 leads from the upper .part thereof and connects with the pipe 8', leading to the governing or throttling valve mechanism 31, which controls the su ply of steam to the nozzles of the engine. Tile valve-seat 'of this governor-- valve appears at 33 and is controlled by 'the valve 32, as clearlyappears in the upper por. tion oi 1. y

Steam is supplied to the turbine at 30 through the late 2Q into the casing 27, the steam being oelivered into the turbine-casing 28 and controlled by the valve32.

lThe upper side of the revoluble receptacle i 2 is provided with concentric spiral corrugations 2", which take hold of the liquid. y

Vl/T'thin the receptacle 9 .l place mercury 5, which descends into the revolving conical reM ceptacle 2 at 9.

The annular receutacle and the i e 8 i i) P leading to the .controlling means'l of thevalve are filled with a lighter liquid, such as glycerin.

The details of this controlling mechanism 31 appear in an application concurrent herewith.

"When the engine .is started, `the shaft 3 is ofcourse revolved, the mercury within the conical receptacle is forced outward by the centrifugal force, and the supply is maintained by the'mercury descending through the vcenter of the Vreceptacledoottom 9 at 9 IOC until, as the pressure continues, the lighter liquid is forced out through the pipe 8 and acts upon the valve-controlling means 31- to close the valve32 against its seat'. As this shuts oil' the supply of elastic fluid to the eligine, the speed of the same decreases and thel mercury is allowed to settle down into the receptacle, rand they controller 31 permits the valve to open and supplies steam to the' thrott-le to again increase the speed. series of IIO these controlling means may be provided land connected to operate successively at different pressures, if desired, so that the control lof the engine is complete by this means.

Having thus described my improved governing means, I desire to state that it can vbe greatly varied in its structural details Without departing from my invention. I have shown my preferred means of gearing the same down to proper speed; but other means could of course be adopted with satisfactory results. I have shown the same in what appears to me as a very simple and effective form. The centrifugal action of the fluid might be secured With other forms of receptacle. I have shown the form that appeals to me as the most satisfactory and effective;

The pressure could of course be obtained by mere revolutions of the fluid Within the receptacle; but I have preferred to supply an ample reservoir that Would deliver into the revolving part and maintain the supply.

Having thus described my invention, what -I claim as new, and desire to secure' by Letters Patent, is#

In a governor for an engine, the combination of a governor-casing supported by'a suitable means; a revoluble `funnel-shaped receptacle, corrugated on its upper surface, on a vertical shaft Within the casing; a Wormgear a-nd Worm as means for driving the same; areservoir above the revolving receptacle, with a central aperture at the bottom; a heavy fluid, as mercury, within the receptacle and reservoir; a pipe connected to the annular chamber surrounding the funnelshaped receptacle, filled with a lighter fluid, as glycerin; a governor-valve; and controlling means for the governor-valve to controlled by the pressure of the liquid. in said pipe, all coacting for the purpose specified.
